Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.

What is a redox process?
A redox process involves the transfer of electrons between reactants, resulting in changes to the oxidation states of the elements involved. Redox reactions consist of an oxidation half-reaction (loss of electrons) and a reduction half-reaction (gain of electrons).
How can one tell if a redox reaction will be nonspontaneous?
The reduction potential plus oxidation potential is negative.
How do you write a balanced equation for the oxidation of sucrose?
The balanced chemical equation for the oxidation of sucrose (C12H22O11) can be written as: C12H22O11 + 12 O2 → 12 CO2 + 11 H2O.
What do you write to name of a compound written as Cu0?
This is the formula for Copper (II) Oxide Copper has two possible oxidation numbers (+2 or +1) since there are no written subscripts for in the formula CuO, copper's oxidation number must have been +2 (If it had been +1, the formula would be Cu2O and the name of the compound woould be Copper (I) Oxide)
What kind reactions are red ox reactions?
Oxidation states have changed.
How is an oxidation half reaction written using the reduction potential chart?
To write an oxidation half reaction using the reduction potential chart, simply reverse the reduction half reaction from the chart. This means changing the sign of the reduction potential value and flipping the direction of the reaction arrow. Remember to balance the reaction by adding any necessary electrons.
What is the total reduction potential of a cell in which sodium (Na) is reduced and zinc (Zn) is oxidized?
The reduction potential of Na is -2.71 V and the reduction potential of Zn is -0.76 V. When Na is reduced, it gains electrons, so its reduction potential is written as a positive value (+2.71 V). When Zn is oxidized, it loses electrons, so its oxidation potential is -0.76 V. Therefore, the total reduction potential of the cell is +2.71 V - (-0.76 V) = +3.47 V.

What is the process of electron gain called?
The process of electron gain is called reduction. For example, if Br gains an electron, its oxidation number is reduced from 0 to -1, and will be written as Br-. The opposite of this (electron loss) would be called oxidation, or ionization.
Half reaction can be written to represent all?
redox reactions by separating the oxidation and reduction processes. Each half reaction shows the transfer of electrons either gaining or losing. When combined, they balance the overall charge and number of electrons transferred in the redox reaction.
